The sunglasses are most likely American Optical AN6531 (thanks to Peter for the alert), with the round nose bar, sweat bar. The glasses have thin metal arms, probably the ones that wrap around the ears, although those details can't be seen in the trailer for the film.

Similar vintage sunglasses are Bausch & Lomb Aviator sunglasses. Bausch & Lomb was the creator of the Ray-Ban brand of sunglasses, but sold the brand in 1999 to the Italian Luxottica Group. During World War II, Bausch & Lomb produced millions of sunglasses for the American army. See a similar pair of vintage aviator sunglasses on the left (picture from styleforum).
